I have a big storage server. 96TB currently with 12 8TB WD drives. My OS is ran off of 2 (RAID1) 240Gb Micron Enterprise SSDs that I got a hell of deal off of on ebay.
I'm looking to speed up my disk reads a little from the HDDs. 90-95% of everything done on the server is read base so no writeback needed. Looking to go with 1 or 2 400Gb Flash Accelerators F40 (maybe something different if it offers better performance/price ratio). Server is running SnapRAID with mergerfs.
Depending on feedback will determine how much cache I should have with 100+ (soon to be 130)TB in a majority read processes. Main question is which processing should I use for my caching? Obviously the drives are already filled so that throws out bcache and there is some mixed reviews with dm-cache on Ubuntu 14 (which i'm running).
Any advice would be greatly appreciated!!!
